WEATHER STRIPPING STRUCTURE FOR CAR WINDOWS Filed Sept. 10, 1936INVENTOR IglEEFI-l Elm- LINK s M v ATTORNEYS Patented Apr. 19, 1938UNITED STATES PATENT OFFICE Application September 10, 1936, Serial No.100,100

4 Claims.

The present invention relates to an improvement in Weatherstrippingstructure for car windows, particularly railway cars, busses, or thelike, and has for an object to provide top weatherstripping to produce aseal between the top of the window sash and the topof the window framewhich Will be effective along theentirelength of the sash, whether ornot the sash is in its truly aligned position or in acocked position,that is,

a position that makes one corner of the sash higher than the other.Quite often this cocked position is brought about by the fact that therailway car openings vary, so that whilesome of them are reasonablysquare others may be considerably out of square. Also the condition maybe produced by warping or strain on the parts of the car structure.

It is proposed to provide Weatherstripping upon the face of the top railof the sash for engage- 20 ment with a vertically disposed angle bar,the engaging surface of the angle bar being relatively wide in avertical direction, and further to provide means for maintaining thesash in tight relation with the angle bar while at the same timepermitting angular variation between them,

With the above and other objects in View an embodiment of the inventionis shown in the accompanying drawing and this embodiment will behereinafter more fully described with reference thereto and theinvention will be finally pointed out in the claims.

In the drawing:

Fig. l is a side elevation of one corner of the upper portion of thewindow structure according 35 to the invention, a portion of the headerstructure being shown in section.

Fig. 2 is a vertical sectional view, taken along the line 22 of Fig. 1.

Fig. 3 is a horizontal sectional View, taken along 40 the line 3-3 ofFig. 2.

Fig. 4 is an elevation of the sash removed.

Similar reference characters indicate corresponding parts throughout theseveral figures of the drawing.

Referring to the drawing in which one end only of the structure isillustrated, the other end being identical, the window structurecomprises side posts ill, a top cross bar ll of L-shape in crosssection,and a sill l2, the side posts being mounted upon the inner framestructure l3 of the car, and the bar I I being secured by screws H tothe header structure M of the car. The sash comprises a top rail l5,side strips I6, and a glass panel H, the side strips being slidablymounted for vertical movement in vertically disposed channel structuresI8 mounted upon the side posts 10.

The top rail l5 of the sash is provided in its nterface with a dovetailchannel l9 extending V 'the full length of the rail and in which thereis engaged a length of Weatherstripping 20, which projects beyond theface of the rail and in the normal closed position'of the window engagesthe vertical inner face of the angle bar H, which inner faceis'con'siderably wider in a vertical direction than the strip 26 andextends for a distance above and below'it, so that the weatherstrippingremains in contact with the bar irrespective of the degree of cocking ofthe window.

Upon the upper edge of the rail Hi there is secured near each end of therail an inverted U- shape spring 2|, the foot 22 upon the inner legbeing secured to the rail by screws 23, and the outer leg being providedat its end with a rounded contact surface 24 which bears upon an angularbearing plate 25 secured to the angle bar II by rivets 26, and whichbearing plate is of a suitable metal designed to reduce friction, asstainless steel, for example. It will be seen that the spring clips archover the bar I l for a sufficient distance to permit of considerablecooking of the window sash, and at the same time the spring pressure ofthe clip pulls the weather-stripping into snug engagement with the innerface of the bar. The rail is preferably provided with two spring clips,one near each end, although windows of unusual length may be providedwith a greater number. It will be noted that the lower edge of thespring ends 24 are above the horizontal plane of the lower edge of theWeatherstripping so that when the upper rail of the sash is engaged withthe bar II, in closing the window, the weatherstripping is engaged withthe vertical inner surface of the bar II before the end 24 engages theouter surface, in other words, before there is any lateral springpressure exerted upon the weatherstripping. In this way the window maybe closed easily, and there will be no tendency for the Weatherstrippingto be pulled out through frictional engagement with the edge of theupper edge of the bar H as the window is closed.

I have illustrated and described a preferred and satisfactory embodimentof the invention, but it will be obvious that changes may be madetherein, within the spirit and scope thereof, as defined in the appendedclaims.

Having thus described my invention what I claim and desire to secure byLetters Patent is:

1. In a window structure, a frame including a top member extending thewidth of the frame,

a window sash including a top rail member arranged to oppose said topframe member, weatherstripping carried by one of said members andprojecting therefrom, the other member having a vertical surface engagedby said Weatherstripping and being greater in its vertical dimensionthan the vertical dimension of said Weatherstripping, and spring meanscarried by said top rail member extending over the top of said top framemember in spaced relation and engaging it only at its side remote fromsaid top rail member to draw said vertical surface and Weatherstrippingtoward each other.

2. In a window structure, a frame including a top member extending theWidth of the frame and having a vertically disposed surface, a windowsash including a top rail member having a vertically disposed surfacearranged to oppose said vertical surface of said top frame member,weatherstripping carried by one of said members along its full width andprojecting therefrom to engage the opposed vertical surface, said lastmentioned vertical surface being greater in its vertical dimension thanthe vertical dimension of said Weatherstripping, and a plurality oflongitudinally spaced spring members carried by said top rail memberextending over the top of said top frame member in spaced relation andengaging it only at its side remote from said top rail member to drawsaid vertical surface and weatherstripping toward each other.

3. In a window structure, a frame including a top member extending thewidth of the frame and having a vertically disposed surface, a windowsash including a top rail member arranged to oppose said verticalsurface of said top frame member, Weatherstripping carried by said toprail and projecting therefrom to engage the opposed vertical surface,said opposed vertical surface being greater in its vertical dimensionthan the vertical dimension of said Weatherstripping, and spring meanscarried by said top rail member extending over the top of said top framemember and engaging it only at its side remote from said top rail memberto draw said vertical surface and Weatherstripping toward each other,the lower edge of said spring means being above the horizontal plane ofthe lower edge of said weatherstripping.

4. In a window structure, a frame including a top member extending thewidth of the frame and having a vertically disposed surface, a windowsash including a top rail member arranged to oppose said verticalsurface on said top frame member, Weatherstripping carried by said toprail member along its full width and projecting therefrom to engage theopposed vertical surface, said opposed vertical surface being greater inits vertical dimension than the vertical dimension of saidWeatherstripping, and a plurality of spaced inverted U-shaped springmembers secured to said top rail member arched in spaced relation oversaid top frame member and engaging it at only its side remote from saidtop rail member to draw said vertical surface and Weatherstrippingtoward each other.
